HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

1,2-Diphenylpyrazolidine-3,5-dione features a rigid, electron-deficient pyrazolidinedione core flanked by two aryl rings, enabling its role in cycloaddition reactions and as a building block for heterocyclic scaffolds. This bench-stable compound integrates readily into synthetic sequences requiring controlled reactivity and structural precision.

Application

1,2-Diphenylpyrazolidine-3,5-dione serves as a stable, bench-ready building block for heterocyclic synthesis, enabling efficient access to pyrazoline and pyrazole derivatives through cycloaddition and reduction reactions. Its dual aryl substitution enhances stability and facilitates purification, while its diketone functionality supports diverse functional group interconversions. Widely employed in medicinal chemistry scaffolds, it functions as a reliable precursor in the construction of bioactive molecules under standard laboratory conditions.
